Mainboard Fails To Activate X,Y,Z axes or X,Y,Z stops

Postby Colin » 04 Aug 2014, 22:56

I have the smaller RigidBot with no LCD or other add-ons.

I run it from a Windows 8.1 computer with the Arduino software installed, and recognizing an Arduino Mega 2560 on COM3.

The assembly was easy and quick with only a few "take apart put back together properly" moments.

When I first powered up my machine the extruder fan started but nothing else does.

The motors made no sound at all and do not respond to any control signals from RepetierHost.

The end stops made no sounds at all.

RepetierHost DOES connect to the printer but that's all it seems to do.

Help?

I haven't tried Repetier, but I assume it's similar to Pronterface and will show you what's going on. Are you getting something like a "low temp" error? If that's the case, you're thermalcouple may be damaged and it seems like that will completely shut down the printer.

Unfortunately this forum isn't getting nearly as much traffic as the Google+ community is. You may want to try over there as well if you haven't already.

What output do you get from M503?

I suggest also looking at the items separately, i.e.:

Do the commands to heat the head and the bed have any effect, do you see temperature rises.
Once or if you have the head set to 180C, can you extrude?
Then you could start to check the steppers.

Well, Pronterface won't install properly on my UBUNTU 14.04 box -- I gather that somebody needs to make PERL functional.

Repetier does install on UBUNTU 14.04 and I finally was able to convince it to 'connect' with my Rigidbot.

Unfortunately, I now see the exact same issue as on my WINDOWS 8.1 box -- the X, Y and Z motors don't run, the heated bed and extruder don't heat up and the the temperature reads 0.00 C

If the thermocouple is damaged or defective it is not obvious from the outside -- I was careful not to damage it while installing.

I'm tempted to just buy a replacement thermocouple from Inventapart, but I'd like to also know if there is anything else that might be wrong.

It sure looks like the main board simply fails to forward any instructions to or from the printer.

Can you post the output you get when you connect?

"Output" as in the list of text messages that I get in the terminal window on my LINUX box?

"Output" as in the many different one-line "Command Waiting" messages in my Repetier printer command window?

Maybe there are logs somewhere with "output" in them?

What helps you the most?

Everything you have really.
The best would be the serial log between the PC and the bot.
And what answer you get when you send an M503.

OK -- I installed Pronterface on my WINDOWS 8.1 computer and I still cannot drive any axis of my printer.

Connecting...
start
Printer is now online.

This was AFTER attempting to update Marlin firmware from 1.0 to 1.1 and you will notice that failed, also.

With no warnings during the update attempt, it just seems not to have worked.

Here are the results of sending an M503 command in Pronterface.

Ok so it looks like the board is connecting to your PC and responding correctly.
"echo:USB Drive init fail" is because it can't find a USB Stick (i.e. no LCD).

So now you should be able to do:

Home:
G28 X0 Y0 Z0
Be ready to press the z stop switch if you think the head will crash into the bed.

Move:
G1 X5 Y5 F6000

For the extruder, but make sure that there is no filament:
M302
G1 E5 F500

If this doesn't produce any movement you will need to check wiring from the main board to the steppers.
